Abstract: The protection circuit includes a micro strip line whose length is equal to a fourth of the wavelength of an amplification signal frequency on a board and whose one side is connected to the input side of a low noise amplifier, a diode whose one side is connected to the other side of the micro strip line and whose other side is grounded, and a capacitor which is connected to the point where the micro strip line is connected to the diode and whose impedance is sufficiently small at the amplification signal frequency. In this configuration, the diode has virtually no effect to the amplification signal component because the impedance of the protection circuit for the amplification signal frequency viewed from the contact point becomes sufficiently high. In addition, for static electricity charged on the antenna connected to the input terminal, the diode is virtually connected directly to the input side of the low noise amplifier because the micro strip line is almost zero in resistance.

Abstract: In such a method and apparatus for detecting microbiological growth in a sealed sample container, pressure within the headspace of the container is monitored for detecting rate of change of such headspace pressure. Presence of microbiological growth within the container is indicated as a function of rate of change of headspace pressure. The rate of pressure change is compared with a standard rate for a family of microorganisms., and growth is indicated when the rate of pressure change (which may be positive or negative) exceeds the absolute value of the standard rate (which also may be positive or negative). For detecting microbiological growths which may have differing growth rates, absolute value of rate of pressure change is compared to a plurality of standard rates for differing families of microorganisms. At least some of the rates may be positive, corresponding to growth of gas-producing organisms, and at least some of the rates may be negative, corresponding to growth of gas-consuming organisms. In either case, microbiological growth in the test sample is indicated when absolute mathematical value of the rate of headspace pressure change exceeds absolute mathematical value of any of the standard rates.

Abstract: Un système, composé d'un procédé et d'un dispositif préféré de mise en oeuvre du procédé décrit, détermine des valeurs de tension correspondant à la durée d'impulsions. Les systèmes connus de ce type présentent des imprécisions lors de la conversion de la durée en tension, ce qui entraîne l'occurrence de non-linéarités. Afin d'éviter ces non-linéarités lors de la conversion, les tensions correspondant à des impulsions dont la durée est utilisée afin d'effectuer la conversion de la durée en tension, sont comparées à la variation dans le temps d'une tension auxiliaire qui sert à former une tension de départ. Cette tension auxiliaire peut être une tension ascendante générée par un générateur de tension ascendante ou toute autre tension appliquée à des composants du dispositif décrit. On peut utiliser ce système de préférence dans un dispositif amplificateur à couches minces qui sert à commander un affichage à cristaux liquides.
